The beat the song is built on is one bar, played through bars 10-11, 13-15 and 18-23, and 2 more places -- 31.1% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on ride, snare and kick, counted in sixteenth notes. On its own it scores 49 out of 100 -- a step up -- and the thing that decides that is how many notes a second it asks for.
The whole song is 56 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
The room opens this beat on its simplest reduction, at 125 BPM, and adds the notes back a rung at a time -- 3 of them. Nothing is a matter of opinion: each rung has a tempo to reach and a gate to pass before the next one.
Tempo goes 125, 145 and 166 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
PRACTISE THIS BEAT →A one-bar groove on ride, snare and kick, in 4/4 at 166 BPM, counted in sixteenth notes. It is written out above, and it covers 31.1% of the bars the kit plays.
Bars 10-11, 13-15, 18-23 and 30-35, and 1 more place. The time is kept on the snare to start with, and it changes 11 times over the song.
49 out of 100 on its own -- a step up. The song as a whole is 56 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
